Janet Jackson's wardrobe malfunction in Super Bowl XXXVIII in Houston tops the list. I mean, what could be worse? Of course, it had no bearing on the game, but no one can get the image of her covering her breast while Justin Timberlake looked on in shock.

Superdome

Terrell Suggs of the Baltimore Ravens accused NFL commissioner Roger Goodell of cooking up the Superdome blackout during Super Bowl XLVII last season. No one's placing blame here. We're just saying you can't play football in the dark. Especially not the Super Bowl.

Barret Robbins

Nobody would ever do this. But Barret Robbins did, leaving the Raiders' team the day before they were to play Tampa Bay in Super Bowl XXXVII. Robbins said he had a manic episode that he attributed to dealing with severe physical pain and mental anguish. Tim Brown and Jerry Rice accused coach Bill Callahan of abruptly changing the game plan, triggering Robbins into such strange behavior. Robbins doesn't remember that, though. What everyone remembers, however, is the 48-21 beating Jon Gruden's Bucs put on the Raiders.

Jim McMahon

You wonder if he wished he could take the moment back. No matter. Jim McMahon of "Super Bowl Shuffle" fame led the Bears to a Super Bowl XX victory in 1986 and was great in the game. Even with his rear end in pain after he took a helmet to his backside. Asked about the injury, McMahon pulled down his pants and mooned reporters. (Paul Benoit/AP)

Eugene Robinson

Let's just put it out there: This is as bad as it gets. Eugene Robinson, a minister and leader for the Atlanta Falcons, was arrested on a charge of soliciting a prostitute the night before Super Bowl XXXIII against the Broncos in Miami. According to one unnamed player's account to the New York Times, players had been visiting the seedy part of town all week, but Robinson got caught offering an undercover cop $40 for sex. He still played in the game, which the Broncos won, 34-19.

Garo Yepremian

The undefeated Miami Dolphins were narrow underdogs against the Redskins in Super Bowl VII in 1973. It ended with what became known as the "Garo Gaffe." On a 41-yard field goal attempt, Yepremian's kick was blocked. When he collected the loose ball, Yepremian attempted to complete a pass instead of falling on the ball. Big mistake. The Redskins' Mike Bass intercepted the pass and returned it 49 yards for a touchdown for the Redskins' only score. The Dolphins kept their perfect season intact with the 14-7 win, but it was a near disaster.

Thurman Thomas

Get your head in the game! Every player has probably heard that at some point—including Thurmon Thomas. The Bills' running back misplaced his helmet and missed the first series of the Super Bowl XXVII game against the Dallas Cowboys. He finished the game with 18 rushing yards.

Jackie Smith

Every receiver drops passes. Usually, it's a missed opportunity that's forgotten about after a few plays. Not this time. Cowboys' quarterback Roger Staubach threw a perfect pass to tight end Jackie Smith in the end zone. Smith dropped it. And the Cowboys lost, 35-31 to the Pittsburgh Steelers in Super Bowl XIII.

Leon Lett

What a 'Lett' down. That's probably what the headlines screamed after Cowboys' defensive lineman Leon Lett's huge blunder. Prancing into the end zone after a fumble recovery, Lett had the ball knocked away at the goal line by the Bills' Don Beebe. The play happened in the fourth quarter of Super Bowl XXVII in Pasadena, Calif. in 1993.

Doug Williams

Doug Williams led the Redskins to a 42-10 victory over the Broncos in Super Bowl XXII, and was the game's MVP. Nothing embarrassing there. But before the game, he was asked the two dumbest questions ever:

"So how long have you been a black quarterback?

There's debate whether that really happened. We hope not. But then there was this gem:

"Doug, would it be easier if you were the second black quarterback to play in the Super Bowl?"

It was mean and unnecessary. It also didn't matter. Bradshaw was named MVP after passing for a then-record 318 yards and four touchdowns to lead the Steelers' to a 35-31 victory.

Fred "The Hammer" Williamson

Trash-talking can come back to bite you in the butt—or knock you flat out. Defensive back Fred "The Hammer" Williamson learned that the hard way. When the Chiefs faced the Packers in Super Bowl I, Williamson spent a lot of time in the run-up talking about what he would do to receivers Boyd Dowler and Carroll Dale: "Two hammers to Dowler, one to Dale should be enough."

It didn't work out that way. Dowler injured his shoulder and Max McGee replaced him, catching seven passes for 138 yards and two touchdowns. Williamson finished the game with three tackles and worse, was knocked out and had to be carried off the field on a stretcher.
